BLE sensor advertisement library

crates.io page docs.rs page

A library for decoding sensor readings from BLE advertisements.

Currently supports:

The actual BLE scanning is up to you, so this library doesn't depend on any particular Bluetooth library or platform. It just provides types and functions to decode the data you give it.

Usage

use std::collections::HashMap;
use btsensor::{bthome, Reading};

// In a real program, this service data would be obtained from a BLE scan.
let service_data: HashMap<Uuid, Vec<u8>> = [(
    bthome::v1::UNENCRYPTED_UUID,
    vec![0x23, 0x02, 0xC4, 0x09, 0x03, 0x03, 0xBF, 0x13],
)]
.into_iter()
.collect();

let decoded = Reading::decode(&service_data).unwrap();
println!("{}", decoded);
